CAR-MOTOR.

SPECIFICATION forming part of Iietters Patent No. 398,723, datedFebruary 26, 1889.

Application tiled March 2l, 1888. Serial No. 267,972. (No model.)v

all 207mm it may concern:

Be it known that I, THADDEUS IV. HEER- Mi-lNs, of Chicago, in the countyof Cook and State of Illinois, have invented certain new and usefulImprovements in Car-Motors, of which the following;` is a specification.

My invention has for its chief objects the application of a steam orother engine to the propulsion of street-cars and similar' vehicles insuch a manner as to render the full power of the engine available forstarting the car and getting it rapidly under way, and, further, toreduce the nlan'ipulatiol'ls necessary for starting` and stoppin g thecar to the smallest possible number and the simplest kind, in order thatthey may be made q uiekl y and with certainty even by conlparativel)vunskilled drivers.

Myinventioll consists in the parts and combinations hereinafterdescribed and claimed.

In. the aceolnpanying,I drawings, Figure l is a side view of the frontpart of a street-car embodyingl my invention, the side of the car beingremoved. to show the interior. Figs. 2 alld are detail views of thesurface con denser it), Fig. I. Fig'. f3 is a front `view of the Caron asmaller scale than Fig. l. Figui is a longitudinal section of the tloorof the ear, showing' the driving' machinery, the point ot' view being'in the opposite side fronl that oi' Fig, l. Fi` 5 is a plan view,partl)v ill seetion, of the ear-axles and the d riving' nlaehinery. Fig.ti is a eross-seetion of the sproeket and brake wheel 2li 2T and :idiaeent parts.

["pon the front 'llatfornl.y il, et' the ear L is located a boiler, l,and engine 5. 'lhe boiler and engine may be of an y suitzlble kind, andare not herein shown in detail, for the reason that they fornl no partin thenlselves of the present invention. For the purpose of carrying outmy invention, however, I have selected as most suitallle an engine andboi ler of the automatic type-that is, in which the supply o'f water andfuel to the boiler and of steanl to the engine are autonlaticallyvregulatedseveral kinds of which are well known and ill nace is fed withliquid fuel in a tank7 Il, on

the roof of the car through a pipe, t, and the supply is automaticallyregulated to maintain a constant boiler-pressure.

The shaft 6 of the engine extends back through the pillow-block 7,bet-ween which and the pillow-block 9 is a frictiol1-clutcll, 8, whichmay be of any approved kind. One part of the clutch S is secured to theshaft 6, and the other to the shaft 42, which is inline with shaft (i,the whole being` on one side of the car, so as to extend under theseats. The clutch S is operated by the fork 43 on the shaft It. Shaft l2(eide Fig. 5) is connected to the axle 2S of the car by the train ofgearing comprising,` the bevel-gears 2l 22 and the spur-gears 13,14, andl5. The spurgears are inclosed in a casing, lo, which surrounds thecar-axle 9S and carries the bearing,` for the gear Il. The admission ofdirt at the axle is prevented by shitting-boxes 25. At the end ofcasing` 1G farthest from the axle 2S is a boss or hub, 24;, in which thecylindric part of casing' l2, which covers the beveLgeals, is ttcd so asto turn easily. The separation of the two casings 1G and 12 is preventedby the pinion 13 alld the bevelgear Q2, which are secured on the shaft-23. The bevclfgear 2l. is fitted to thecasing l2, so as to revolvefreelytherein, end lnotion being' f ented by the beari ng l t). Saidbevehgear :free to lllove endwise on shaft if, but is compelled torevolve therewith by nlealls of a feather ill the shaft. lllc easing' l.is sup ported ill wavs ll on the ez'lr-tioor, Figs. i and i, which allowit to slide baek and forth without disturbing its alignment. The effectof the construction justdescribed is to pernlit the free pla;Y of thesprings between the ear and axles without alleeting the drivinggearing,the rise and fall of the car-axles producing simply a slight movement ofthe casing l 2 ill the slide il. and of the bevel-gear 21 on the shaftt2.

Keyed upon the ealsaxle 2S is the brakedruln 27 and sprocket-wheel 2li,they being 1lrei'erablyeast ill one piece,as shown. A secondspreeketi-wheel, 235, is keyed to axle 29 andthe two wheels areconnected by the chain 3b'. A easing', 37, surrounds the wllole andexcludes di rt, havingx stu llingdloxes 3S 3S upon the axles for thispurpose. The brakc-bands 30 are held at one end bylthc pin hwllicll issecured IOO to the casing 37, and are attached at the other end to theoperating-lever 33, which vibrates on the pin 341-, and is connected bythe rod 2O to the arm 1) of the shaft te, before men- 5 tioned asoperating the clutch-fork 43. The brake-bands are adjusted by theset-screws 32 abutting against the pin 31. Attached to the arm 19, or toa similar arm on the same shaft, 44e, is a rod, 18, which extends to thedrivers lever 17.

Upon the roof of the car is located a tank, 41, for holding the oil fueland a surface condenser, 40, the latter being' shownin detail in Figs. 2and 2. It will be seen to consist of a series of pairs of corrugatedplates of sheet metal united by suitable return-bends, a set beinglocated on each side of the roof, the whole affording a large area ofradiating-sun face.

The detail. views, Figs. 2 and 2a, show the construction of thecondenser. The returnbends b have openings on their flat side fitted tothe corrugated plates @,which are so joined as to form a series of tubespractically. Vide Fig. 211.) The plates a and return-bends l) may besoldered or brazed together. The exhauststeam is led to the condenser bythe pipe 39, which enters a cross-pipe, 45, at an elevated point. r1`hecondensed water is drained off at the rear and` carried to a tank belowthe back platform. This tank is not shown, as its connection with theother parts is easily understood without an illustration.

The feed-pipe til, conveying the water from the feed-pump 47 to theboiler 4L, is provided with a pipe, 41S, which is connected to the feedpipe at a pointintermediate between the check-valve 50 and thepump 1Tand leads to the condenser 40. 1n said pipe LS is a cock or valve, 51,which may be opened to allow the water from the feed-pump to pass to thecondenser and assist in cooling it when the boiler is sufliciently full.The valve 51 may be operated by hand or a float in the boiler, such asis commonly used to control the feed.

r1`he pipes and connections of the boiler and engine are omitted, exceptso far as they are necessary to illustrate the invention; but they maybe readily supplied by the skilled work` man.

The operation of my invention will be easily understood without furtherexplanation. The engine being once started may be allowed to runcontinuously, the starting and stopping,` of the .car being effectedwholly by the manipnlation of lever 17, which, it will be seen, puts thefriction-clutch in operation and releases the brake when thrown forward,and throws out the clutch and applies the brake when thrown back. Bythusrunning the engine continuously and at full speed its full power isavailable for starting the car, which may thus be done quickly, and thedrivers attention is concerned with only one, and that a very simple,operation.

Provision may be made for reversing-gear either on the engine or inconnection with the bevel-gears 21 and 22 (eide Fig. 5) by an additionalbevel-gear on shaft 23 opposite to gear 22, and arranging for gear 21 tomesh in either in a Well-known manner; but such an additionalcomplication and source of confu* sion are to be avoided except inspecial cases.

I have shown the axles of the car connected bya chain gearing; but it isobvious that connecting-rods such as are used on locomotives, or anyequivalent therefor, might be used, or that on level tracks suchconnection might be uimecessary.

1. The combination, in a car-motor, of a continuously-ruiming engine, ashaft in axial line with the engi 11e-shaft, a clutch connecting saidshaft with the engine-shaft, driving mechanism connecting thefirst-named shaft to the car-axles, a brake, and a single leverconnected to and operatingsaid clutch and brake.

2. The combination of the conti nuously-ru nning engine 5, the clutch S,the shaft 42, and gearing connecting the same to the car-axle, thecross-shaft 441, having the clutch-fork 43 and arm 19 thereon, thebrake-operating rod 20, the drivers lever 17, and connecting-rod 18.

The combination of the casings 16 and 12, pivotally connected to eachother and inclosing the train of gearing and the slide 11, as and forthe purpose set forth.

4. The combination, in a car-motor, of an engine upon the platformoutside the car, a shaft at one side of the car extending longitudinallybeneath the seats and driven through a clutch-connection by said engine,gearing connecting said shaft to the car-axles, a brake, and a singlelever connected to and operating both the brake and the clutch,substantially as described.
